Text: An Introduction to Statistical Methods and Data Analysis by Lyman Ott & Michael Longnecker, 5th Edition,2001

Course Objective: As stated in the preface of the text book "...to prepare students to deal with solving problems encountered in resaearch projects, decision making based on data,, and general life experiences beyond the classroom and university..."

Organizational Matters:

Grading: 
Lab assignments:  100 pts         approx. weekly (9 lab assignments)

Exam I:                100 pts         Feb 26  (location to be announced)

Exam II:               100 pts         Apr   8 (location to be announced)

Final Exam:         200 pts         May 5   (12:00-2:00 p.m.,tentative)

Final Grade:

Final course grades will be determined by  total points earned from the labs and exams according to the schedule above divided by 500 and expressed as percent. The final percent will be used to rank students and determine cut-off points for assigning letter grades. First, letter grades A, B, C, D, will be assigned  to those with  percentages in the  ranges  90-100, 80-89, 70-79, 60-69 respectively. The cut-off points may be  adjusted (lowered) later depending on the performance of the entire class to increase the proportion of students in the class earning each grade. Plus/minus grades will be assigned to scores near final cut-off points.
Exams:
Lectures and Assignments: Please read the assigned chapter(s) prior to the start of the lectures. My lectures will cover the same concepts, but I will often use different examples and may use a different presentation. It will probably help to reread the chapter(s) after the relevant lectures  and  do the suggested exercises.  A set of typed notes, used as overhead tranparencies in class, is also available on the web pages as postscript and pdf files. Students may print these out if they wish.

Laboratory
:
Scheduled lab time will be used for several different activities:
It is urged to use the lab time well. Use it to ask questions on or for more explanation of topics you did not understand well during the regular lecture.

Lab Assignments:    Lab assignments are distributed and due at the lab session.  Intent of these assignments is to increase understanding of concepts learned introduced  in lectures and  to gain practice in applying these concepts and associated computations.   Discussion with friends and classmates is fully encouraged in completing these assigments. However, copying  of others work  is not a good way to learn and will not be tolerated. Late homework will not be accepted.

Computing: This class focuses on statistical concepts, not details of a specific computing package. We will use JMP  in class and examples of their use are available on the web pages.  No attempt will be made to give details of  the use of the language for general data analysis nor is it expected  that students become experts in the use of JMP.  The TA will help you with JMP. JMP is available under MS Windows in Carver 205 and Durham 139 .   For those who are interested in learning more about JMP, the JMP documenatation  "Introductory Guide" and the "User's Guide" available in the same folder as the JMP software on the desktop is adequate. JMP HELP ROOM in 0113 Pearson is open daily during 9-5.
